Thanks! It is nice to have this project finished, complete with new refines and everything! The brave effect on their weapons is quite nice, and I'm generally a fan of the flyer class, so it's easy to activate.
I like the bonds as well! They turn her into a great speed tank with good sustain, thanks to Renewal. And I think she has access to Swap, although I pretty much always keep Draw Back on her. Draw Back gives her more mobility than Swap, especially on the first turn, since it also lets her pull an ally forward, giving her an effective movement range of 3. It also keeps an ally next to her when she's using it to advance into the enemy's range.
Thanks! Congrats on your sixth merged unit as well! Any ideas on your next project?

Given the pending update, you can essentially just ignore the bane, simplifying the choice to just that between +Atk and +Spd for the boon. For my 5*+10 Fir, I went with +Atk over +Spd. Without the Atk boon, she'll be pretty much totally dependent upon specials to do damage. She really appreciates a bit more attack, moreso, in my opinion, than speed. So the Atk boon is what I recommend.

The sisters are finally complete! I was able to give Palla the refine she was waiting for, and so now I'll post all 3. I had posted Est a long time ago, but I haven't posted the other 2 here yet. I'm posting Est again, though, since she has an updated skill set, as I'd like that to be the pic I have on here (as opposed to the older one). Enjoy the Whitewings!
This now means I'm up to 6 5*+10s!

But the mythic blessings only benefit the whales, and, while there is a cap on how much anyone can benefit from the mythic blessings, the introduction of the blessings did nothing but only further widen the gap. I don't particularly take solace in the fact that there's a cap because this whole situation created a problem where there was none before. It puts whoever doesn't acquire multiple blessings via summoning at an inherent disadvantage, and this problem will be replicated again for when new mythic heroes are released. One will need to pull multiple copies of those in order to remain competitive when they come out. This will be ameliorated over time, as they start to make blessings available through other means, but, until then, this is all to the detriment of F2P players.
As for me just potentially quitting the mode, it's not simply because of rank, it's because the problems with the mode hinder my enjoyment of it. I'd like to see them address the problems.

I was able to rise once more to T21, securing another crown for my Feh's head. At a few hours before close, my score of 3,733 was ~400 or so marks above the cutoff. That's a reasonable lead, but certainly not what it once was. There has been a rather significant score inflation, even for non-Fjorm+Water weeks!
It did, indeed, hold! I'm happy to hear that your serious run also managed to get you back into T21 as well (and by a much larger margin than mine!).
Honestly, I've found that people have been pretty tight-lipped about what the cutoff mark for Arena Assault is. It could also just be that those around the edge don't regularly visit this thread, or otherwise don't share their AA scores.

Last week's score of 3,730 wasn't nearly enough to cut it, given the amount of score inflation due to Fjorm being the bonus hero during water season. However, it was adequate to keep me in T20, so I've another opportunity to rise using Laegjarn as my bonus hero. I obtained a score of 3,733 this time, and it looks like this should be more than enough. I'm at 1,412, while the cutoff is 2,885, which means I'm still in the top 10% for the group. While I'm sure that this will go down some, the buffer is substantial enough that I think it should be adequate.

Like some others have already stated, I agree that there should be no particular "ultimate" cap. Rather, I'm fine with them periodically raising the cap a little at a time, as they have been doing. The current 5k cap has likely been more than enough for most people, but I do expect them to raise the cap on that at some point. I think an adjustment to 6k sometime soon sounds like a reasonable ask. I see no reason to currently project a limit, given they can keep raising the limit over the lifespan of the game.

I'm at 3,730, and this is no longer a sufficient score, as I'm now below the cutoff. Lots of score inflation! This, however, should be more than adequate to keep me in T20, so I can try again next week, when Fjorm is no longer the bonus unit. I believe in you Laegjarn!

Sure enough, my words to @Vaximillian were true:
I finally decided to give my Palla a Slaying Edge+ a couple weeks ago, and, lo, now IS has announced the weapon upgrades for the Whitewings...! Yes, you all can thank me for finally upgrading my Palla's weapon. It was the moment they were waiting for. Here's my Palla in her current glory:
But I'm excited for this! I'm hoping the Whitewing weapons are quite good.

I like to lead with the bonus unit if I can, which leave me relying on the color of my allies to knock out the color quests. But, if it's late in the round and they're being uncooperative, I'll switch to the colors I need on non-multiplier hours.
We're having the same problem with red over here on Team Laegjarn! We've had sufficient enough VGs by now that people should know better. Of course, it's usually the randos, so it's a bit difficult to communicate with them...

Why must the randos on Team Laegjarn always lead with red? Ugh! So annoying. For the past several matches, I've had to cycle through over 5 resets each just to get non-red randos. I'd like to get my quests done, thanks! At least no one on my FL is doing it.

Thanks! My score is 3,730 right now, we'll see how it goes. It should definitely be enough to stay in T20, but will it be enough for T21 this week? Perhaps. This score range has usually been enough, but it is water season with Fjorm as a bonus hero, so there's going to be a lot of score inflation this week. We'll see if it's enough!
